Well, I plugged them in and the left driver doesn't even work. Tried it on 3 different systems, even tried 2 other cables. I opened them up and one of the wires wasn't soldered correctly and I don't have a soldering iron and I've tried way to hard to resolve the issue. I don't even know where else to take this, do I contact like support of some kind and request a new pair with a proof of purchase?
